Evaluation of Motor Skills in Children with Rubinstein-Taybi Syndrome.

Rubinstein-Taybi syndrome (RTS) is a rare genetic disease that associates intellectual disability with somatic characteristics. We have conducted a study of the overall motor abilities of RTS participants. Static postural performance as well as gait parameters were somewhat decreased, although not significantly compared to typically developing (TD) participants. In contrast, the motor skills requiring a high level of visuomotor coordination were considerably degraded in RTS participants compared to TD participants. We also found that cognitive status was significantly correlated with performance for tasks requiring a higher level of visuomotor coordination in RTS but not TD participants. Our study demonstrates a reduction in the motor performance of RTS participants and a link between the level of intellectual disability and motor capacities.
